Method
Mix the butter, caster sugar and vanilla extract until just evenly mixed. Stir in the flour and cornflour. Wrap in clingfilm and chill for about 30 minutes.
Roll out to the thickness of a $1 coin and cut out different sized heart shapes. Bake at 180C/160C Fan/Gas 4 for 10 minutes. Leave to cool on a wire rack.
Make the icing sugar and divide into small bowls to add pink and red food colouring to the mixture. Now it’s time to decorate your heart biscuits!

To give biscuits as a gift, pack in a DIY box, which you can print here. To make the box more interesting you could decorate it or print it out on some pretty card.
